The 100% stacked bar chart renders chart data without any spaces/margins on the right side of the chart. The sample below uses the default settings for the X and Y axes.

I tested in Power BI desktop version 2.72.5556.701 64-bit (August 2019) with default setting for the 100% stacked bar chart. There is a margin on the right side of the chart. Please update Power BI desktop version then test again.

Hi @v-qiuyu-msft ,
Sorry about that. Please see uploaded image. As you can see, there's barely any margin on the right side of the chart. The chart uses the default settings (except for colors) and the X axis is hidden.
